Once you get this part of the quest chain you walk back out toward the stairs that would lead up to Kalogarn and go to the opposite side of the Iron Council's hall. Once you explore it go back to the NPC that gave you this quest and he'll give you the 4 quest, which require you to complete the bosses on hard mode. I'm assuming after this you'll get a quest for hard mode Yogg'Saron up to Algalon.

Complete all four quests to enable the quest Algalon from Prospector Loren.Simply speak to the Archivum Console to complete the quest, rewarding Celestial Planetarium Key.

Once you obtain the discs and begin this quest, Make sure you return to Prospector Loren before you continue killing bosses, otherwise you will have to wait till next week to turn in this quest and continue the chain.

If you are having issues getting the next quests or getting your sigils to drop, make sure you are on the correct quest for the instance, 25m or 10m. I couldn't figure out what was going on until I realized I had a second disk and started the quests on 10m.
